# RPG Tools
Simple RPG helper tools for generating content for tabletop role-playing games
(or any other game that uses maps).

Currently `rpgmap` is the only available tool but more are planned:

* Non-player character (NPC) generator
* Town generator
* World-map generator
* ... (ideas welcome)

## RPG Map
`rpgmap` is a grid-based map generator. This is the primary tool available
right now.

Example maps look like this:

```
rpgmap -x 50 -y 50 --num-rooms 50 --room-size 7
```
![Example halls map](doc/images/halls_50x50.png)

```
rpgmap -s cave -x 50 -y 50
```
![Example caves map](doc/images/caves_50x50.png)

The two primary room types are `halls` (default) and `cave`. Halls represt a
classical rogue-like dungeon; rooms are rectangular and placed randomly on a
grid and then connected by single-width hallways. No effort is made to ensure
that the rooms overlap, which creates interesting non-rectangular rooms when
they overlap.

Caves are organic-looking blobs that are created by filling the grid with
random cells and then annealing using a cellular automata mechanism. This
creates blobs that vaguely resemble water-carved caves. The cellular automata
strategy can produce blobs that are not connected, when this occurs, they're
removed (if too small) or connected via a hallway.

Maps have an orange square that appears near the middle, which is intended to
be the entrance.

Note on aesthetics: I am not a capable artist and the maps are kind of ugly. To
be improved in the future.
